GAS' FlREPLACE-HEATER.

SPECIFICATION forming part of Letters Patent No. 787,657, dated April18, 1905.

Application ledDecember A13, 1904. Seria-1 No. 236,709.

To all whom, itmrt/ concern:

Be it known that I, QUIMBY S. BAcxUs, a citizen of the United States,residing at Brandon, in the county of Rutland and State of Vermont, haveinvented certain new and useful Improvements in Gas Fireplace Heaters;and I do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

My present invention relates to gas-heating devices for offices anddwelling-houses, and more particularly to the class of the same gencrally denominated fireplace-heaters, and is'an improvement therein forfacilitating' the placing of the same in such rooms and the lire# placesin the same.

In the d rawings I have shown the best form in which Ihave contemplatedembodying my invention` and the same is disclosed in the fol- ``/iowingdescription and claims.

In the d rawings` Figure 1 is a front view of my improved gas-heater.Fig. 2 is a transverse vertical section of the same. Fig. 3 is avertical sectional view of the regulatingvalves made longitudinally ofthe burner. Fig. 4 is a vertical sectional view of the same transverselyof the burner.

In the drawings, A is the front or face of the heater.

B is the opening or recess to receive the gasburner and water-log.

The front plate A is provided at its sides and top with arearwardly-extendinginclined flange a. This flange is provided withnumerous openings, which are preferably made in the form of anornamental open-Work to permit the colder air to enter at the bottom andto again return tothe room through the openings at the upper part of thesides and top. The flanges a and the face A form a shallow casing ofdishing configuration. In the lower part of this casing is a shallowfireplace B, formed by the back b, which is connected to the face A andcurves backward to or near a line connecting the rear edges of theflanges a and then extending downward to the bottom of the casing. andend pieces closing the ends of the space thus formed, leaving the hollowjambs a a', the spaces within which are conplate tance below the burneris a pan or receptacle E for holding water, and a covering-plate E issupported from the burner with its upper edge in close proximity to theflame of the burner, while its lower edge for the whole or part of itslength extends downward into the water-pan E to convey heat to vaporizethe water to supply the requisite moisture to the air of the room. Y

To the back of the face of the casing above the iireplace is placed asteam-radiator F, which is preferably constructed of thin metal and isof considerable extent vertically, but quite narrow, so as to present abroad surface from which the heat of the steam may be radiated. Thewater-log is connected at each end by a pipe extending outwardly throughthe ends of the fireplace-niche and then upwardly to the radiator F.One-of these pipes is see'n in Fig. 2 at f. l

It will thus be seen that all of the heating devices are placed withinthe space defined by the face-plate A and the Hanges a, thereby enablingthe device to be placed before a fireplace like a ireboard, or in casethere should be no fireplace in the room the device could be placedagainstthe wall of the room to give the semblance of a fireplace withoutin any way disturbing or defacing the wall.

In the burners employed in this class of devices the gas is caused toenter the same in a jet, which draws in with it a sulflcient amount ofair to secure complete combustion and to produce the blue flame which isfound to give the greatest amount of heat. It is desirable that thesupply of gas shall be under the control of the person using the heater,so that a greater or lesser Haine may be produced, according to theamount of heat de- IOO sired. The jet of gas is ordinarily controlled bya needle-valveg but where the amount of heat is regulated bymanipulation of this valve alone a great waste of gas is often caused bythe users turning the valve to admit an undue amount of gas, so thatthere is not perfect combustion of the same.

In Figs. 3 and 4 I have shown a valve construction by which I connectthe gas-supply to the burner, which avoids the evils above noted andenables the valves to be adjusted to take up wear and prevent leakage.In Fig. 3, Gr is the needle-valve casing for furnishing the jet of gasto the mixing-chamber of the burner. g is the needle-valve, the stem ofwhich is screw-threaded and works in a threaded aperture in the wall ofthe casing. The outside of the casing is provided with the recess g', inwhich is placed one or more rings of asbestos packing b. Upon the stemof the valve is mounted the nut or gland g2, having the tubularextension g3 to enter the recess g. In assembling the parts of theheater the needle-valve g is turned to give such a flow of gas as willgive perfect combustion at the burner. The nut g2 is then turned toforce the packing tightly in place. This prevents all leakage betweenthe thread of the stem and the casing and acts also as a jam-nut to holdthe valve from easy displacement. Should any leakage occur at any timeby reason of the parts having been subjected to heat, further pressureby turning the nut g2 will make all tight again. The gas is admitted tothe needle-valve chamber or casing through a valve or cock H. This valveor cock may be of ordinary construction; but I prefer to employ the formshown in Fig. 4L, in which the tapering valveplug H' is secured in placeby asbestos ring packings L, the ring if loosely encircling the stem ofthe valve and the securing-cap H2. The gas is turned on or off byopening or closing the Valve H, and as the valve Gr always remains thesaine perfect combustion is assured. rIhe partial turning off of thevalve H will lessen the flame, but retain approximately the sameadmixture of air, as the jet of gas will have less velocity and willtake with it into the mixing-chamber a less amount of air.

What I claim, and desire to secure by Letl ters Patent, is-

1. A gas-heater comprising among its meinbers, a face-plate having atits top and sides inclined flanges extending rearwardly and forming withthe face-plate a shallow casing, the rear edges of said flanges ending1n the Vsame vertical plane, and heating devices located wliolly withinsaid casing, whereby the flanges of the casing can be placed against aplain wall without defacing the same, substantially as describedc 2. Ina radiating gasheater, the combination of a face-plate having inclinededges forming a shallow casing with a burner, a waterlog andsteam-radiator, connected with said water-log located within saidshallow casing,

substantially as described.

3. In a radiating gas-heater, the combination with a face-plate havinginclined edges forming a shallow casing, of a gas-burner, a water-log, asteam-radiator connected with the water-log, the water-pan and means forconveying heat to the water in the pan, the whole located within thesaid shallow casing, substantially as described.

4. A fireplace-heater comprising among its members, a face-plate havingat its top and sides rearwardly-extending inclined flanges forming ashallow casing, said casing being provided with a fireplace nicheextending rearwardly to or near to the plane of the rear edges of saidflanges, a heating device within said fireplace-niche, and a connectedradiating device within said casing above said fireplaceniche, saidheating devices being located forward of the vertical plane of the rearedges of the said anges of the casing, substantially as described.

5. A gas-heater comprising among its inem` Q. S. BACKUS.
